The 80% gas furnaces are design
certified by SA for use with natural and
propane gases as follows:
As a ategory I furnace, it may be
vented vertically with type B-1 vent
pipe and also may be common
vented as described in these
instructions.
This furnace should be installed in
accordance with the American National
Standard Z223.1 - latest edition booklet
entitled “National Fuel Gas ode”
(NFPA 54) (in anada, SA B149.1 and
.2 Installation odes for gas burning
appliances), and the requirements or
codes of the local utility or other
authority having jurisdiction including
local plumbing or waste water codes.
The National Appliance Energy
onservation Act (NAE A) of 1987
states that any gas furnace
manufactured after January 1, 1992,
must have a minimum Annual Fuel
Utilization Efficiency (AFUE) of 78%.
The higher the AFUE percentage the
more usable heat energy the consumer
gets for every dollar of fuel purchased.
This is similar to the EPA's minimum gas
mileage requirement for automobiles. It
gives the consumer a relatively easy
way to make direct efficiency
comparisons between different furnace
brands and styles.
A high AFUE value, which translates into
a low operating cost, is not the only
concern that consumers have. They also
want a furnace with a reasonable
installed cost. They want a furnace that
provides them with comfort – their main
concern. And they expect a furnace with
exceptional reliability and longevity.
Gas furnace manufacturers are always
striving to provide consumers with the
best furnace value. The Low Profile
Furnace addresses all those consumer
needs. It gives exceptional efficiency
with a low installation cost. It delivers the
comfort the customer wants along with
the reliability they expect.
The key to all these customer benefits is
the furnace's heat exchanger. The
materials used to construct the furnace
in general and the heat exchanger in
particular make it a rugged, long lasting
unit. The unique heat exchanger design
provides the customer with a furnace
only 34 inches high. This gives the
consumer a unit easily installed in
almost every location that accepts all
customary accessories.
With the introduction of higher efficiency
furnaces, special attention must be paid
to the venting system. Only listed
venting systems may be used as stated
in the installation instructions and the
National Fuel Gas Code, ANSI Z223.1
(NFPA 54), or the Canadian CAN/CGA
B149.1 and B149.2 Installation Codes
for Gas Burning Appliances. Since
furnace technology and venting
requirements are changing, awareness
of local, state, and federal codes and
industry changes is imperative.
GENERAL INFORMATION
IMPORTANT INFORMATION
ABOUT EFFICIENCY AND
INDOOR AIR QUALITY
entral cooling and heating equipment
is only as efficient as the duct system
that carries the cooled or heated air. To
maintain efficiency, comfort and good
indoor air quality, it is important to have
the proper balance between the air
being supplied to each room and the air
returning to the cooling and heating
equipment.
Proper balance and sealing of the duct
system improves the efficiency of the
heating and air conditioning system
and improves the indoor air quality of
the home by reducing the amount of
airborne pollutants that enter homes
from spaces where the ductwork and /
or equipment is located. The
manufacturer and the U.S.
Environmental Protection Agency’s
Energy Star Program recommend that
central duct systems be checked by a
qualified contractor for proper balance
and sealing.

NOT : Always perform a proper heat

furnace size. This ensures that the
furnace is sized to adequately,
economically, heat the building and
provide the correct airflow for your
application.
